Ever wanted to know how much data your DPM servers are churning?  Perhaps you are looking to implement DPM2DPM4DR and want to know how much data you'll be transferring across you WAN, or perhaps you are investigating what storage to purchase and need this data to make an informed assessment.  Well this is how you calculate your churn, it's easy to do but a bit time consuming as it's not possible to export data from the Jobs view.

1. Open the DPM console, select the Monitoring pane and the Jobs tab.
   
   
   
2. Click Create Filter from the Actions pane.
3. Give your new filter a name and select a 24 hour period.
   
   
   
4. Within the Filter options field, select the Jobs tab and place a check in the following job types and select all the job status's.  
   • Consistency check
   • Replica creation
   • Synchronization
   
   
   
   
5. Select the Protection tab and make select Group by Protection Group from the drop down menu and select All.  If you have a check placed next to External tape jobs, remove it.
   
   
   
6. Select the Other tab and un-check any libraries that are selected.
   
   
   
7. Click OK to create the filter.
8. Select the new filter from the Filter names drop down menu and order the results by the Data Transferred column.
   
   
   
9. Now simply add up all the data transferred values to get your data churn rate per day.  In my case I have the grand total data churn of 0.26MB as you can see in the image above.

In my example I have deliberately created only four jobs so it's easy to view.  In your production environment though you could hundreds of jobs so adding up the data transferred values can take some time.  If I work out a way to make this simpler, I'll be sure to let you know.

Hopefully that will be helpful to you.
